I have had this problem for a week now where the computer will randomly lock up. Pressing ctrl+alt+del results in a dark screen for a couple of minutes and a message saying windows security and shut down options failed to load. I believe this is a Trojan.sirefef.an because of windows defeder alerts, but every time I run a Malwarebytes full scan it detects 5 items and the computer will lock up as stated above. Here are the logs Attach.txt DDS.txt

Welcome to the forum.

Before we proceed further, please uninstall or disable uTorrent and any other peer-to-peer filesharing app.

Continued use of filesharing or ill-advised downloads will surely re-infect your system.

It's also against the forums policy concerning P2P programs:

Here you go......

Please read the following information first.

You're infected with Rootkit.ZeroAccess, a BackDoor Trojan.

BACKDOOR WARNING

------------------------------

One or more of the identified infections is known to use a backdoor.

This allows hackers to remotely control your computer, steal critical system information and download and execute files.

I would advice you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation.

Though the infection has been identified and because of it's backdoor functionality, your PC is very likely compromised and there is no way to be sure your computer can ever again be trusted. Many experts in the security community believe that once infected with this type of trojan, the best course of action would be a reformat and reinstall of the OS. Please read these for more information:

I will try my best to clean this machine but I can't guarantee that it will be 100% secure afterwards.

Let me know what you decide to do. If you decide to go through with the cleanup, please proceed with the following steps.

-----------------------------------------

Please read the directions carefully so you don't end up deleting something that is good!!

Please download the latest version of TDSSKiller from here and save it to your Desktop.

  • Doubleclick on TDSSKiller.exe to run the application, then click on Change parameters.

  • A reboot will be needed to apply the changes. Do it.
  • TDSSKiller will launch automatically after the reboot. Also your computer may seem very slow and unusable. This is normal. Give it enough time to load your background programs.
  • Then click on Change parameters in TDSSKiller.
  • Check all boxes then click OK.
    2012081517h0349.png
  • Click the Start Scan button.

    Any entries like this: \Device\Harddisk0\DR0 ( TDSS File System ) - please choose Skip.

    Note: If Cure is not available, please choose Skip instead, do not choose Delete unless instructed.
  • A report will be created in your root directory, (usually C:\ folder) in the form of "TDSSKiller.[Version]_[Date]_[Time]_log.txt". Please copy and paste the contents of that file here. There may be 3 logs > so post or attach all of them.
  • Sometimes these logs can be very large, in that case please attach it or zip it up and attach it.

Here's a summary of what to do if you would like to print it out:

If a suspicious object is detected, the default action will be Skip, click on Continue

If you get the warning about a file UnsignedFile.Multi.Generic or LockedFile.Multi.Generic please choose

Skip and click on Continue

Any entries like this: \Device\Harddisk0\DR0 ( TDSS File System ) - please choose Skip.

Ensure Cure is selected, then click Continue => Reboot now to finish the cleaning process.

Freezing could be caused by a lot of things including hardware problems. (over heating)

The RK log is clean.

AV: Webroot SecureAnywhere *Enabled/Updated* {9C0666FC-6C7D-3E97-3C40-0C6B33FC7401}

SP: Windows Defender *Enabled/Updated* {D68DDC3A-831F-4fae-9E44-DA132C1ACF46}

SP: Webroot SecureAnywhere *Enabled/Updated* {27678718-4A47-3119-06F0-3719487B3EBC}

By your logs you have Webroot SecureAnywhere and Windows Defender running at the same time, you can't do that.

I suggest you disable Windows Defender:

Then...........

Please Update and run a Full Scan with MBAM, post the report.

Make sure that everything is checked, and click Remove Selected.

the same with Webroot.

Let me know, MrC

Have you tried turning off the service:

If you really, really want to make sure that it never comes back, you can also open up the Services panel through Control Panel, or by typing services.msc into the Start Menu search or run boxes. Find Windows Defender in the list and double-click on it…

And then you can change Startup type to Disabled.
